CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/894,066, filed Feb. 12, 2018, entitled RAILYARD CREW MEMBER VEST FOR USE WITHIN A RAILYARD, which is incorporated herein by reference in its entirety and made a part hereof.

FIELD OF THE INVENTION

The present invention relates to railcars and, more particularly, to a railyard crew member protection system for use within a railyard.

BACKGROUND

A railyard, railway yard or railroad yard is a complex series of railroad tracks for storing, sorting, or loading/unloading, railroad cars and/or locomotives. Railroad yards have many tracks in parallel for keeping rolling stock stored off the mainline, so that they do not obstruct the flow of traffic. Railroad cars are moved around by specially designed yard switchers, a type of locomotive. Cars in a railroad yard may be sorted by numerous categories, including Railroad Company, loaded or unloaded, destination, car type, or whether they need repairs. Railroad yards are normally built where there is a need to store cars while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations.

Many railway yards are located at strategic points on a main line. Main line yards are often composed of an Up yard and a Down yard, linked to the associated railroad direction. There are different types of yards, and different parts within a yard, depending on how they are built.

In all railway yards, a very dangerous action is performed when bringing railcars together and or apart. This action may be called a Shove Move which is the process of pushing a cut of cars or pushing a train from the rear and then coupling the cars together. Coupling utilizes a device located at both ends of all cars in a standard location to provide a means for connecting one railcar to another. A switching crew uses the locomotive to couple to and uncouple from railcars. The switching crew must communicate by radio, as the engineer in the cab of the locomotive usually cannot see where a long cut of cars is going, and relies on the crew member on the ground guiding them into position.

In these situations, there is always an opportunity for human error whenever a significant amount of verbal communication is required, and this will sometimes result in damage to person or property. The danger is that the locomotive engineer has no idea when the cars are being shoved or coupled without the assistance of ground personnel. Because of the danger of the shove and coupling move, the locomotive engineer also has no idea of the impact speed and the distance of the railcar. If the impact speed or distance is improperly determined by the locomotive engineer or ground personnel, the impact and coupling can cause damage to thousands of freight cars and millions of dollars of damage to couplers. In several cases, these accidents can cause injuries and even death to employees.

An objective standard to determine whether the railcars are moved safely is a desirable check to make sure the crew will not be impacting anything other than the next railcar targeted for coupling. A need exists for continuing to attempt to have complete visibility of people and machines in a railyard and providing real-time visual depiction of where a railyard crew is located within the railyard.

The real-time camera system 140 may provide a real-time transfer of information via videos and pictures without a delay or lag. Additionally, video and pictures may be stored remotely on the railyard site computer.

FIG. 5 illustrates a smart vest 100 with an environmental monitoring system 150. The environmental monitoring system 150 may be connected to the vest processor 105. The environmental monitoring system 150 may include a humidity sensor. The environmental monitoring system 150 may include a temperature sensor that may sense both the outside air temperature and/or the railyard crew member's body temperature. Additional environmental factors may be monitored by the environmental monitoring system 150 without departing from this invention. The environmental monitoring system 150 may detect dangerous conditions for the railyard crew member, such as: hypothermia, hyperthermia, heat exhaustion, dehydration, heat stroke, or frostbite, etc. Additionally, the environmental monitoring system 150 may track a railyard crew member's last water intake and/or rest and/or work schedule. The vest processor 105 may send the information/data from the environmental monitoring system 150 to the railyard site computer for further analysis and action, such as remedial training and/or corrective actions for the railyard crew members.

FIG. 6 illustrates a smart vest 100 with a high-accuracy location system 160. The high-accuracy location system 160 may be connected to the vest processor 105. The high-accuracy location system 160 may utilize both GNSS (global navigation satellite system) and RTK (real-time kinematics) technologies to provide the ability to enable centimeter location accuracy with the high-precision GPS. The high-accuracy location system 160 may include an RTK module 162 and a GPS antenna 164. The RTK module 162 may be for example a UBLOX NEO-M8T model. The RTK module 162 may provide and deliver high-integrity, precision timing in demanding applications world-wide. The RTK module 162 may include enhanced sensitivity and concurrent constellation reception to extend coverage and integrity for challenging signal environments. The RTK module 162 may include timing integrity measures with Receiver Autonomous Integrity Monitoring (RAIM) and continuous phase uncertainty estimation. The RTK module 162 may feature high dynamic range radios with both analog and digital interference mitigation, supporting applications in wireless communications equipment. Other similar RTK modules or processors may be utilized with these features that are known and used in the art.

GNSS stands for “global navigation satellite system” which is standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. RTK stands for “real-time kinematics” which is generally a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (GNSS) such as GPS, GLONASS, Galileo, Beidou and other regional systems. RTK uses measurements of the phase of the signal's carrier wave, rather than the information content of the signal, and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimeter-level accuracy. FIGS. 9 and 10 further illustrate the high-accuracy location system 160.

FIG. 9 illustrates an example generic high-accuracy location system 900 via GNSS and RTK. The high-accuracy location system 900 may include a GPS receiver 912 on a station whose position is known exactly, a base station 910. The base station 910 receiver's computer can calculate its position from satellite data from a GNSS satellite(s) 920, compare that position with its actual known position, and find the difference. The resulting error corrections can be communicated from the base station 910 to a rover station 930. The errors are constantly changing so the base station 910 will monitor the errors continuously, at least when the rover receiver or receivers 930 are working. While this is happening, the rover stations 930 move from place to place, collecting the points for positions relative to the base station 910. Then, the base station 910 corrections and the rover station's data 930 is combined together through a data link in real-time, or may be applied later in postprocessing. Additionally, the number of carrier cycles from the satellite 920 to the rover stations 930 may be determined and used to calculate the range of the rover stations 930.

FIGS. 10A and 10B illustrate how an example high-accuracy location system 160 may be configured within a railyard 10. The high-accuracy location system 160 may include a base tower or reference tower 910. The reference tower 910 location is a confirmed and static location within the railyard 10. The high-accuracy location system 160 may also include an RTK rover station 930A for a railyard crew 15 via the smart vest 100 and an RTK rover station 930B for a locomotive 20. The high-accuracy location system 160 may include a wireless communication network 940 that connects each of systems throughout the railyard 10, such as providing Wi-Fi communication between the reference tower 910, railyard crew 15, and the locomotive 20. By using the Wi-Fi communication, the communications stays within the railyard 10 and the communication does not rely on a cellular network and/or cellular service.

FIG. 10B specifically illustrates the steps of the high-accuracy location system 160 within the railyard 10. First (310), the reference tower 910 location is established within the railyard 10 at a static location. Next (320), the GNSS satellite 920 location is continually sent to all locations within the railyard 10. Next (330), the rover station RTK 930A on the railyard crew 15 establishes an accurate location of the ground crew 15 through the GNSS satellite 920 and the RTK 930A. Next (340), the rover station RTK 940A on the locomotive 20 establishes an accurate location of the locomotive 20 through the GNSS satellite 920 and the RTK 940A. Throughout the process (950), Wi-Fi communication is provided between the reference tower 910, railyard crew 15, and the locomotive 20 through the Wi-Fi tower and system 940 within the railyard 10. Lastly (960), the high-accuracy location system 160 provides the location and video of the crew 15 and locomotives 20 within the railyard 10.

FIG. 7 illustrates a smart vest 100 with a mobile power unit 170. The mobile power unit 170 may be connected to the vest processor 105. The mobile power unit 170 may provide power to the vest processor 105, the smart vest 100, and other systems on the smart vest 100. The mobile power unit 170 may be a low-cost battery pack that may be used to typically recharge phones. The mobile power unit 170 may be 8,000 mAh with 2.1 A output. Other power output may be utilized with the mobile power unit 170 without departing from this invention. The mobile power unit 170 may include an LED battery status indicator 172. The LED battery status indicator 172 may include a 4-dot LED indicator or other numbers of dots without departing from this invention. The mobile power unit 170 may be capable of at least 40+ hours of operation or other time amounts without departing from this invention. The mobile power unit 170 may be recharged with a standard micro-USB port 174 or other recharging methods known and used in the art. The mobile power unit 170 may have more or less weight which will generally lead to more or less power in the unit.

FIG. 8 illustrates a smart vest 100 with a real-time communication system 180. The real-time communication system 180 may be connected to the vest processor 105. Generally, the real-time communication system 180 may include the two-way radio 112 which may be connected to the vest processor 105. The vest processor 105 and the real-time communication system 180 may record audio. The audio may be analyzed through speech and text means. The audio may also be analyzed to help signal intent and moves within the railyard. Additionally, the smart vest 100 may include buttons that can send commands over the radio 112 to provide redundancy of communications.

Additionally, as illustrated in FIGS. 11A and 11B, the smart vest 100 and the vest processor 105 may detect the “state” of the railyard ground crew 15. For example, as illustrated in FIG. 11A, one or more railcars 20 may be located on the rails of the railyard. It is important in these situations to determine the position of the crew 15. The high-accuracy location system 160 may be utilized to determine the position of the crew 15 with respect to the railcars 20. The position of the crew 15 may be determined as: 1) between cars/tanks 20 assuming we know the location of the equipment; 2) whether the crew 15 is riding on the railcars 20 based upon their height with respect to the ground; and 3) whether the crew 15 is on the tracks 30, near the tracks 32, or far from the tracks 34. Through the use of the smart vest 100, this information may be visualized in the cab of the railcars and/or a central location within the railyard 10 that monitors the safety situation within the railyard 10. FIG. 11B specifically illustrates how the smart vest 100 and the high-accuracy location system 160 helps to define the state based on the height of the railyard crew 15. As has been described above, the high-accuracy location system 160 has the capability to determine high-precision location to not only include ground location, but also height or distance from the ground. Because the high-accuracy location system 160 determines a height, the state of the railyard crew 15 may be determined based on a certain height 40. Below a certain height 44, the railyard crew 15 may be determined to be on the ground. If the crew 15 is determined to be on the ground, there may be an unsafe condition if within the rail and within a certain distance of the railcars 20. If the crew 15 is determined to be on the ground, the crew 15 may be safe if they are located away from the railcars 20. Above a certain height 42, the crew 15 may be determined to be riding on the railcar/tank 20. Generally, in this situation, the crew 15 may be determined to be safe. Additionally, equipment position information (if available) could be used for a safety redundancy check.

Additionally, in another embodiment of the present invention, the data from the smart vest 100 and the vest processor 105 may be transmitted to a geo-stationary communications satellite and/or a cellular system to one or more remote receiving station(s). The receiving station may transmit the data via the Internet to a web based portal which is accessible by a user via a workstation. Data collected and transmitted can be from any smart vest 100 or vest processor 105. As was described above, the smart vest 100 or vest processor 105 may feature a number of additional data collection outputs. Outputs from all of the data from the smart vest 100 or vest processor 105 may be combined together to electronically represent the status or condition of the railyard 10, railyard crew 15, and/or locomotives 20.
